SOURCE: Technics SU-V2 keeps cutting out

An amp will cut out if the output protection circuit kicks in. This circuit compares output power against the preset level. Each channel has it's own, independent protector. There are calculations that can be done, but for a novice the rule of thumb is to "never use a speaker with a power rating less than the amp AND a lower impedance than stated". Typically using a 4 ohm load on a 8 ohm system is inviting disaster. Even if the system does not become a smoke generator, you might notice that though "louder", the sound quality is deteriorated. Many "audiophiles" often hook up some combinations of speakers to have "surround" without really understanding that the collective impedance actually changes (generally lowers).

SOURCE: Technics SU-G95 Amplifier and no sound on left speakers

Usually this is a defect in the output amp IC. If you have no experience with repairs of these types of units, have it checked by a service shop. If the output AMP IChas failed, it will cost about $75 for a replacement. This unit uses an RSN3306P IC .

2 dead amps, am I dreaming that I could ever fix them is it even worth it... Sansui Au-101 & Technics SU-X302


it is always good to take on a project from which you will learn a lot
everything is fixable and in the case of electronics it takes a fair amount of electronic knowledge before you begin
You are obviously very keen to do this so you have to start from the right angle to have any chance of success
first you will need a full schematics of the circuitry so that you can see what works what and what is happening after the next component
next get beginner electronic books to get the right ideas and approach because if you know what each component is supposed to do in the circuit it makes it easier to understand a result when you do something
finally all electronic shops uses an oscilloscope when testing circuitry as it shows the wave pattern produced and the voltage after each component
example --- a capacitor shows a stop/ start pattern , ac current shows a wave pattern, dc current a flat line and much more
keep at it but be aware that the project will take time and if you surround yourself with technical publications and the right equipment you will get it working
remember it takes a qualified electronics technician around 5 years of learning to do what you hope to achieve at home

Technics SU-G75 has no sound


Hello
when the resistors are burned,means that the transistors are damaged, or the power module is damaged.
and in your case its the power module.
Hope this helps.

SU-G86PP-K Technics Amp speakers just quit works good, sounds good, and then goes quiet sometimes wait 5 - 10 minutes and they come back on other times, wait till next day ??????


Check for wire shorts as this changes the impedance and will over heat the thermal cutoff. Too long of wires or too small diameter can do this. If no joy with this, suspect bad speaker or blown amp...
